To take advantage of price slump caused by whatever?
I bought 0.1 coins.
I did not bought a thing at that point because I still was taking that the price was to high so I did not buy them, I only like to buy when the price is low for me.
With Bitcoin the price is only going to higher and higher so eventually you will have to buy if you want to have a chance to make more money.
I think the bitcoin price will trade above the $600 for the next few weeks. $600 could be a good price to buy.
